Interventricular septal motion is studied in sixty tow cases classified into 3 groups; Gr. 1-right ventricular volume overload (RVVO); Gr. II-combined right ventricular volume overload and left ventricular volume overload (RVVO + LVVO); Gr. III-combined right ventricular volume overload and right ventricular pressure overload (RVVO + RVPO).
A linear relationship was obtained between the right ventricular dimension index (RVDI) obtained echocardiographically and the magnitude of the left to right shunt at the atrial level (Qn/Qs).
Two rare instances of false negatives in a hemodynamically insignificant left to right shunt and in a large ASD are reported.
Modification of abnormal septal motion in Gr. II and Gr. III is studied.
Lesion specific features of certain anomalies i.e. Ebstein«SQ»s anomaly, total anomalous pulmonary venous return (TAPVR) and endocardial cushion defects (ECD) are discussed.
